Collective Studio is a family-run shorts manufacturer in Narayanganj, Bangladesh. Shorts are the jogger's summer twin and the tee's natural partner, and they share the same floor, the same fabrics and the same 150-piece minimum per style and colour. What changes is the proportion: a short uses far less cloth than a jogger, so the waistband, the pocket bag and the hem carry a larger share of the price and of the quality.

Three decisions define a short. The fabric family: brushed fleece or French terry for sweat shorts, cotton or cotton-modal jersey for lounge and sleep shorts, and lightweight jersey, mesh or a performance blend for gym shorts. The weight: sweat shorts sit between 280 and 400 GSM, with 320 to 360 the premium band, while gym and lounge shorts sit between 140 and 220 GSM. The inseam: five inches reads athletic, seven reads casual, nine reads basketball, and the difference is a pattern decision, not a fabric one.

The waistband is where sweat shorts are won or lost. The standard build is a covered elastic waistband with a flat drawcord through metal or embroidered eyelets; a jacquard logo waistband, with the brand name knitted into the elastic, is the upgrade that makes a short look like a far more expensive garment. Gym shorts usually carry a wider, softer elastic with an internal drawcord and a brief liner where the fabric is sheer. Pockets follow the jogger logic: side-seam pockets sit inside the standard price, zipped pockets add a trim and an operation, and a back patch pocket adds one panel.

Two construction details decide whether a short survives a season. Compacting: cotton fleece and terry shrink, so we pre-shrink the fabric mechanically before cutting and wash-test the pre-production sample, so the inseam you sign off is the inseam after washing. Hems: a coverstitched hem lies flat on terry, a folded and topstitched hem suits fleece, and a raw or curved hem is a streetwear choice that needs a stable fabric to avoid rolling. Our joggers page covers the waistband and cuff builds in more depth.

What we make: sweat shorts, gym and training shorts, lounge and sleep shorts, board-style knit shorts for beachwear ranges, and children's shorts, all cut and sewn from your pattern with organic cotton available under our GOTS certificate RSC 9687. What we do not make: woven chino, tailored or cargo shorts, which our sister buying house sources as a separate order. A matching set with a hoodie or tee is booked from the same dye lot so the pieces match in daylight.

If you are comparing shorts manufacturers, ask each whether the fabric is compacted before cutting, what the waistband elastic and drawcord are, and whether the quote is DDP; then ask for a live video call from the floor. Ours is at Plot-A-132, Road No. 02, BSCIC Industrial Area, Panchabati, Narayanganj 1420, and the GSM converter translates the weights above into ounces if that is how you think.

Three fabric families, one floor

Fleece and terry sweat shorts, jersey and modal lounge shorts, lightweight jersey and mesh gym shorts, cut and sewn to your pattern from 150 pieces.

Waistbands that hold

Covered elastic with a flat drawcord as standard, jacquard logo waistband optional, wider soft elastic with an internal cord on gym shorts.

Pre-shrunk, wash-tested

Cotton fleece and terry are compacted before cutting and the sample is wash-tested, so the inseam you sign off is the inseam after washing.

Low MOQ — from 150 pieces

150 pieces per style, per colour, with sizes split freely inside it and matching sets booked from one dye lot.

What to specify for custom shorts

Shorts have fewer parts than a hoodie, but each one decides the fit. A brief that covers these points gets an accurate first sample:

Inseam and leg opening for each size, measured flat. Inseam alone does not fix the look: the same 18 cm inseam reads very differently with a wide or a narrow leg opening. Front and back rise, which decides where the shorts sit. The waistband: width, elastic or rib, internal or external drawcord, and whether the drawcord ends are tipped or knotted. Pockets: side-seam, slanted or none, plus any back or zip pocket. Hem: coverstitched, raw-cut on French terry, or a rib cuff on a jogger short.

Our free shorts tech pack template covers every one of these points, with a filled-in example; give the inseam and leg opening for the length you want.

How a shorts order runs, from brief to delivery

A shorts order runs in four stages, and launch dates are easier to plan once you can see where the time goes.

Brief and swatches. You send a tech pack, a sketch with measurements, or a short you already sell for us to measure, and we send fabric swatches in the weight you've chosen. Sampling, about 10 days. We cut and sew a sample from your pattern. The pre-production sample is wash-tested, so the inseam you sign off is the inseam after washing. Production, 40 to 50 days after you approve the sample. The fabric is knitted and dyed in lots, compacted before cutting, then cut, sewn and finished on our own floor in Narayanganj, and finished pieces are measured against the sealed sample before they ship. Freight, on top. We ship DDP, so duty and delivery are handled for you; transit depends on sea or air and on your port.

If the shorts are half of a set with a hoodie or tee, say so in the brief: both garments' fabric is booked from the same dye lot, which is worth planning at the start rather than adding later. The launch-date calculator counts back from your on-sale date.

Checking your shorts sample: five tests before you approve

A sample short always looks finished on a table. These five checks tell you whether it'll still be right after a summer of wear:

Wash it, then measure it. Measure the inseam, leg opening and waist flat after a wash and compare them with your spec, not with the sample before washing. Stretch the waistband. Pull it to full stretch a few times; it should lie flat again rather than ripple. Check opacity under stretch. On a light gym or lounge short, stretch the fabric over your hand in daylight. If it goes sheer, the fix is a denser or heavier fabric, a darker shade or a liner. Sit down in it. The rise decides whether the short pulls at the back or gapes at the waist, and you only find out seated. Look at the hem. It should lie flat after the wash; a raw or curved hem that rolls means the fabric isn't stable enough for that finish.

Tell us what you'd change and we adjust the pattern before the pre-production sample, so the bulk order is made to the version you've actually tested.

What moves the price of shorts manufacturing

A short uses less cloth than a jogger, so the waistband, the pockets and the hem carry more of the price than they do on a longer garment.

Fabric family and weight

Fleece and terry are bought by the kilo, so a 360 GSM sweat short carries more cloth than a 180 GSM gym short, and brushing fleece is an extra mill process. Performance blends and mesh for gym shorts price per kilo differently again.

Waistband build

Covered elastic, a flat drawcord and eyelets are three bought-in trims with their own minimums, plus the channel-stitching operation. A jacquard logo waistband replaces the plain elastic with a knitted one and costs a knitting minimum rather than a print run.

Pockets and liners

Side-seam pockets are formed in seams that already exist. Zipped pockets add a zip and an operation each; a back patch pocket adds a panel; a brief liner in a gym short adds a second fabric and its own seams.

Compacting and hems

Pre-shrinking the fabric is charged per kilo before cutting, and the hem finish is an operation: coverstitch, fold-and-topstitch, or a curved hem with a facing each take different minutes on the line.

Colourways and sets

Every colour is its own dye lot and its own 150-piece minimum per style. A short sold as a set with a hoodie or tee has its fabric booked from the same lot, which is worth planning at the start rather than adding later.

Pattern and volume

Grading a short across sizes with inseam options is a one-off cost shared across the order, and a short pattern nests efficiently on the marker, so fabric waste is low and unit price steps down at the usual breaks.

Questions about shorts manufacturing, answered

What is the minimum order for custom shorts?

Our minimum for custom shorts is 150 pieces per style, per colour, and you split the sizes inside that however your customers buy. The fabric sets that floor: fleece, French terry and jersey are knitted and dyed in lots, and a lot only runs as production at around a hundred and fifty pieces. Every colour is its own dye lot, so a short in black and in grey is two minimums, or 300 pieces. A short sold as a set with a hoodie or tee is a second style with its own 150, and we book both garments' fabric from the same lot so they match. For a first order, one colour run deep usually teaches you more than three colours run thin, because reorders show you which second colour your customers want. Grading across sizes is a one-off cost shared across the order, so the unit price falls as quantity rises. Our MOQ calculator adds up a shorts-and-hoodie set across colours.

What fabric weight should sweat shorts be?

Sweat shorts should be 280 to 400 GSM (grams per square metre), with 320 to 360 GSM the premium band most brands settle on: heavy enough to hold a shape, light enough for summer. French terry's open loops let a summer short breathe and dry quickly; brushed fleece is softer and warmer, but on a cheap base yarn it pills sooner. Gym and lounge shorts are a lighter product at 140 to 220 GSM, in jersey, cotton-modal jersey, mesh or a performance blend. Weight is the largest single price lever after colour count, because fleece and terry are bought by the kilo and brushing fleece is an extra mill process, so a 360 GSM short carries noticeably more cloth than a 180 GSM one. Tell us your season and market and we will send swatches; if you think in ounces, the GSM converter translates any of these weights.

Do you make custom mesh gym and basketball shorts?

Yes: gym, training and basketball-length shorts are cut and sewn to your pattern in lightweight jersey, mesh or a performance blend at 140 to 220 GSM, from 150 pieces per style and colour. The usual build is a wider, softer elastic waistband with an internal drawcord, plus a brief liner where the fabric is sheer, which on training shorts is standard. A basketball-length short sits at about a nine-inch inseam; a training short nearer five. Fibre is the first decision. Polyester dries fastest and suits kit that is washed hard, while a cotton-rich blend suits gym-to-street shorts rather than real sweat. If you want an all-over print, sublimation commits the short to polyester, and it needs a light base because it prints no white. Recycled performance blends are available too; the recycled-content paperwork is issued by the partner mill, and we hold GOTS only, so ask us before putting a recycled claim on the finished short. Our activewear page covers performance fabrics, seams and opacity in more depth.

Can I get organic cotton shorts?

Yes: organic French terry and fleece sweat shorts, from 280 to 400 GSM, can be made in our GOTS-certified facility, RSC 9687, and we send the scope certificate on request. When a retailer or marketplace asks for proof on a specific order, we provide a transaction certificate for it. A little stretch does not rule it out, because GOTS allows a small share of elastane in the blend. The blend decides the label wording, though. Under GOTS's label grades, a garment with at least 95% certified organic fibre can be labelled "organic"; from 70% up to that point, the grade is "made with organic materials". A polyester or nylon mesh gym short cannot carry the certification at all, so an organic range is usually sweat and lounge shorts rather than training kit. We confirm which grade your blend qualifies for before anything is printed on a label. Budget for the premium that certified fabric carries when you ask us to quote.

What inseam length should custom shorts have?

Choose the inseam by how you want the short to read: about five inches is athletic, seven casual, nine basketball-length. It is a pattern decision, not a fabric one, so the same terry or fleece can run at any of those lengths. We grade with inseam options so you can run two lengths from one pattern, for example a five-inch and a seven-inch terry short, and we quote the second length for your order. On a short, rise, thigh and inseam are graded on their own steps rather than in proportion to the waist, so the leg length is set for each size instead of growing with the waistband. The pre-production sample is wash-tested, so the inseam you approve is the inseam after washing, because cotton fleece and terry shrink if they are not compacted first. If your customers already like the length of a short you sell, send us one and we will take the measurements from it directly.

Can you add a liner to gym shorts?

Yes, we can add a brief or boxer liner in a lightweight mesh or jersey, and on training shorts it is standard. The liner is a second fabric with its own seams, so it adds to the price, but it solves opacity on light-coloured performance fabric. What stops a short going sheer is how densely the fabric is knitted and how heavy it is, not its stretch; stretch actually opens the knit, and pale and heather shades give way before dark ones of equal weight. That is why we check it under stretch, never flat on a table, and our QC team, led by Walter Meyer, checks opacity again at final inspection. A lined short usually pairs with the wider, softer elastic waistband and internal drawcord. We will show you the short on the sample with and without it if you are undecided.

Do you make chino, cargo or tailored shorts?

No, not on our own floor: chino, cargo and tailored shorts are woven garments, and our floor cuts and sews knitwear only. Those woven styles go to our sister buying house, CMB Sourcing Ltd, which sits in the same industrial area and handles them as a separate order. CMB is a separate company, so that part of your range sits on its own contract, introduced by us. What we do make is the knit answer to a smarter short: a fleece or French terry short cut to your pattern, with side-seam pockets inside the standard price, a back patch pocket that adds one panel, or zipped pockets that each add a zip and a sewing operation. A jacquard logo waistband is the upgrade that makes a knit short look like a far more expensive garment. Send the knit and woven shorts together and we split them between our floor and CMB. Our services page shows what the sister buying house covers.

Do you make board shorts?

Yes, in knit: we make board-style knit shorts for beachwear ranges, cut and sewn to your pattern from 150 pieces per style and colour. Our floor cuts and sews knitwear only, so a woven board short goes to our sister buying house, CMB Sourcing Ltd, a separate company, as a separate order, if it is within their range. Beach shorts are worn wet and sandy and washed often, which shapes the build at pattern stage: a looser fit, and seams that are usually flat rather than overlocked. Fibre decides how long the colour lasts in the sun. Polyester resists UV fading far better than cotton. On cotton, reactive dyes bond with the fibre and outlast pigment dyes, which only coat the surface. Navy, black and natural also outlast intense reds and bright blues. If a retailer needs a lightfastness rating, we can arrange the test. Swimwear is a separate discipline, priced separately; our beachwear page covers both.

How long does it take to make custom shorts?

Plan on about 10 days of sampling, then 40 to 50 days of production after you approve the sample, then freight on top. Sampling starts once we have your tech pack, or a short you already sell for us to measure, and your fabric choice. The pre-production sample is wash-tested, so the inseam you approve is the inseam after washing. The production clock starts at approval rather than at your first email, because the bulk fabric is ordered against the approved sample: it is knitted and dyed in lots, compacted before cutting, then cut and sewn on our own floor in Narayanganj. Freight depends on whether you ship by sea or air and on your port, and we ship DDP, so duty and delivery are handled for you. Each round of sample changes adds time, so a complete brief is the quickest route to bulk. The launch-date calculator counts back from your on-sale date. From order to your door, plan on about 70 days by air.

Can you make shorts as part of a matching set?

Yes. The usual pairings are a sweat short with a hoodie or sweatshirt, a gym short with a tee, and a lounge short with a jersey top. Each garment is its own style with its own 150-piece minimum per colour, so a black short and a black hoodie make 300 pieces, and the same set in two colours makes 600. Sizes split freely inside each 150. The reason to brief the set together, rather than adding the short later, is colour: when both pieces are cut from the same fabric, we book it from one dye lot at the start, so the pieces match in daylight. A short ordered months after the hoodie comes from a new lot and can sit a shade off, which customers notice when the two are worn together. A jacquard logo waistband on the short is a neat way to carry the set's branding into the bottom half. Our MOQ calculator adds up a set across colours and styles.
